Core Tip

Core tip: In this study, we evaluated the minimally invasive endoscopic management of near-total benign fibrotic strictures of the proximal esophagus involving the hypopharynx across the pharyngo-esophageal junction. Both patients were successfully treated using a novel approach: stricture dilatation (with a 10F co-axial diathermic dilator and through-the-scope balloon) followed by the electroincision of residual adhesions at the hypopharyngeal base with a wire-guided sphincterotome. To the best of our knowledge, this report represents the tightest esophageal or hypopharyngeal strictures ever opened endoscopically and reported in the literature.
